I am 66 so can really relate to what you are going through. I am not sure which is correct, your stats under your name or those on your ticker. If it is the ones under your name, as we get closer to goal the loss really slows down.

After we have been on plan for a longer period of time we might start cutting things down. Journal for a week and make sure you are getting in everything on the protocol sheet, especially the oil. Get some fattier type choices in your
regular protein meal, such as some beef.

If you eat at the top rnd of what you are allowed on the sheet (all your veggies etc) you will likely see a shake up.

Oh by the way, you mentioned weight loss slows down after 40. Maybe a bit but nothing like in our 60s. I wish I could lose like I could when I was 50!
You hubby lost quicker than you because he has much more muscle. We woman really lose a lot of muscle over the years making it much harder to lose as we get older.
